Vejret i Siem Reap (Angkor) i januar

Siem Reap's forum rates January as one of the best months to visit Cambodia — hot by day, 28-32°C, but noticeably less humid than the wetter months. Regulars say a light wrap only really earns its keep for a pre-dawn tuk-tuk ride to catch sunrise at Angkor Wat, or on an over-air-conditioned bus — otherwise it's shorts-and-sunscreen weather with strong UV even on an overcast day.

Regulars are direct that temperatures here are essentially guaranteed to top 35C this month, though generally less humid than the peak of July, with the standard workaround being an early start, a midday retreat to a pool and air conditioning, then heading back out again late in the afternoon. Our row backs that hot, genuinely dry read, 35C reading as a scorching 40C, over 24.3C nights feeling 28C, with rain light at 36.9mm across 6.4 days and humidity at 65 percent. Regulars are consistent some visitors do manage this month and even April despite the intensity, while others avoid it deliberately, the temples themselves offering little shade regardless of timing. Sun protection and a genuinely early start remain the standard advice throughout. The record: 11 hours of sun, a 13.1 kph wind and AQI 78.

Siem Reap-forum threads asking if April is simply too hot don't sugarcoat it - one thread calls the month stinking hot, brain-bakingly hot, everything parched, brown and dusty, with daytime temperatures well into the 40s Celsius on the worst days. Regulars offer the same standing advice: start sightseeing at first light, retreat for a long midday siesta somewhere air-conditioned with a pool, then go back out in the late afternoon once the worst heat breaks. A tuk tuk ride is recommended over an enclosed car, since the breeze dries off sweat rather than trapping heat the way air conditioning does when you step back out. Khmer New Year lands in April too, and mango season is in full swing. The midday temples empty out fast as visitors retreat indoors. The record: a scorching 35.3C by day feeling like a punishing 41C, 25.4C nights, 74mm across 10 days, 67 percent humidity, an unhealthy 77 AQI and 11 hours of sun.

Siem Reap-forum threads on November weather call it the downhill side of the wet season - locals treat November through January as their cold season, bundling up for the mornings until around 9:30 or 10am even though visitors mostly find it warm rather than cold. The standard itinerary follows that same schedule: Angkor tours start around 8am while it's still cool, wrapping up by midday once it gets too warm to keep walking. The monsoon is winding down but still unpredictable enough that a poncho is standard advice, with any downpour usually arriving in a concentrated morning or evening window rather than spread through the day. Posters call the November-to-mid-January stretch one of the best climate windows of the year, which is exactly why it's also peak season. The record: 31.5C days feeling like a sticky 37C, 23.6C nights, 98mm across 12.9 days, 79 percent humidity and 9.4 hours of sun.

February is the last comfortable month at Angkor. It is firmly inside the dry season - our row gives 15.5mm across 2.9 days - and the mornings are still among the year's coolest, which matters when the plan is a sunrise at the temples. What regulars warn about is the dust, because months without rain leave the roads and the causeways powdery, and about the direction of travel: February is where the temperature begins its climb towards 39 or 40C by April. Tonle Sap still has enough water for the boat trips in this month, which stops being true later. It is high season, so the temples are busy. The record: 32.8C days that feel like 36C, 21.9C nights, humidity 61 percent and 10.6 hours of sun.
